Unagi is the Japanese name commonly used for freshwater eel, especially when prepared as kabayaki. The eel is usually filleted, grilled, and brushed with a sweet-savoury glaze, then served with rice or in sushi.
Unagi tastes rich, mildly sweet, and savoury, with a soft, fatty texture. Its distinctive flavour often comes as much from the caramelised kabayaki glaze as from the eel itself; it is not usually strongly fishy.
Yes, unagi in sushi is usually cooked, not raw. It is commonly grilled with kabayaki sauce and served over sushi rice or rolled with rice and other fillings; raw eel is not the standard unagi sushi preparation.
Unagi usually means freshwater eel, while anago refers to saltwater eel. Unagi tends to be richer and fattier, whereas anago is often lighter and softer; Japanese restaurants commonly grill or simmer them in different styles.
Unagi sauce is typically made by simmering soy sauce, mirin, sake, and sugar until glossy and concentrated. Recipes vary, and some commercial versions use different proportions or additional ingredients, so the flavour can range from subtly sweet to quite rich.
Kabayaki unagi is filleted, deboned, skewered, grilled, and repeatedly brushed with sauce. Preparation differs by region in Japan: some cooks steam the eel before grilling, while others grill it directly for a firmer, smokier finish.
Usually, yes: unagi refers to freshwater eel in Japanese cooking. The name is used broadly on menus and packaged foods, though, so it does not always identify one exact eel species.
Eat unagi warm, often over steamed rice as unadon, or as a topping for sushi rice. The eel is already cooked, so use chopsticks or a fork and enjoy it with the accompanying sauce; pickled vegetables can balance its richness.
Unagi provides protein and is a source of vitamin B12 and omega-3 fats, but kabayaki sauce can add sugar and salt. It can fit into a varied diet; enjoy it as one component of a meal rather than relying on it as a health remedy.
Refrigerate leftover cooked unagi promptly in a sealed container and eat it within a few days. Reheat it gently, covered in a pan or oven, to keep it from drying out; frozen leftovers should be thawed safely and heated through.

Unagi refers to eel prepared in the Japanese kabayaki style: filleted, grilled, and brushed with a sweet-savoury tare, usually based on soy sauce. The glaze turns glossy and lightly caramelised, while the eel stays tender, rich and distinctly savoury.
In Japan it is commonly served hot over steamed rice as unadon or unaju; it also appears as a sushi topping. Outside Japan, it is often found on Japanese restaurant menus in rice bowls or sushi rolls. Its 18.4 g of protein per 100 g makes it a substantial choice, though the glaze adds sweetness and the fish itself is rich. Pair it with plain rice and crisp vegetables, or ask for less sauce for a lighter meal.
High
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
